Compute the correction of the exchange coefficient between the fluid and the wall for a turbulent flow.
This is function of the dimensionless distance to the wall
.
Then the return coefficient reads:
This coefficient is computed thanks to a similarity model between dynamic viscous sub-layer and themal sub-layer.
is computed as follows:
The final exchange coefficient is:
| [in] | prl | laminar Prandtl number |
| [in] | prt | turbulent Prandtl number |
| [in] | ckarm | Von Karman constant |
| [in] | yplus | dimensionless distance to the wall |
